Ubuntu is the hype distribution of the moment. They sure have a zealous community, but it's not enough to get a good distribution. Do their technical and philosophical progress make it so great and better than our precious Mandriva?
Well, it's certainly not the fact that it's based on a sexist distribution, neither their printing support using CUPS, neither their Samba support, neither their devotion to the free-software cause by providing proprietary applications (like drdsl) and firmwares. Linux in a binary world would be so great!
They state to their live system is faster, but from my tests, the difference is not that huge, there is a lot of room for improvment, since it's sometimes awfully slow (20 minutes to boot? nice improvment!).
Finally, they certainly did a good look and feel polish job. They also provide great user-friendly software install tools, like the "Add/Remove Applications" tool (gnome-app-install, see french documentation) and the adept installer, using the ddtp (debian description translation project).
But is that worth the whole ongoing buzz?
